apache flex - What is the error :a conflict exists with inherited definition flash.display:DisplayObject.mouseX in namespace public?

Question

This appeared as I was trying to use a mouseEvent to move an object. I placed the variables for mouseX and mouseY in the public class. I did the same for direction X and Y but there was no error message for those.

Answer 1

If the class you are adding the mouseX to is extending the DisplayObject type (and if it's any kind of Flex component than it does), you already have a variable with that name from that type. As a fix name your variable something else eg. myMouseX. If you don't know what exactly I'm taking about with extending classes, check the tutorial on Object-oriented programming in ActionScript.
